Evidence Snapshot
Lion's Mane: 5 human RCTs cited • NGF / BDNF mechanism well-characterised • Evidence grade: GOOD
Cordyceps: CS-4 exercise RCT positive in older adults • Strongest in clinical populations • Evidence grade: MODERATE
Non-overlapping pathways — combining both is biologically sensible
Most people frame this as a competition. Lion's Mane or Cordyceps. Brain or body. Pick one.
That framing misses the point entirely.
These two mushrooms work through completely separate biological pathways. Lion's Mane (Hericium erinaceus) stimulates nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF) production in the brain. Cordyceps (Cordyceps sinensis) influences cellular energy metabolism, NAD+ synthesis, and oxygen utilisation at the mitochondrial level. They do not compete. They do not even overlap. Understanding this — what we call the dual-channel principle — changes the entire conversation from "which one?" to "which one first?"

Lion's Mane: What the Human Trials Actually Show
Lion's Mane has earned its reputation as the cognitive mushroom — and for once, the marketing largely matches the science. The active compounds are unique to this species: hericenones from the fruiting body and erinacines from the mycelium. No other edible mushroom produces them in meaningful quantities.
The mechanism is unusually well-characterised. A 2026 hypothesis-driven review (PMID: 41683696) summarises how erinacines potently induce NGF and BDNF synthesis, while hericenones potentiate downstream signalling via PI3K/AKT/mTOR and MAPK/ERK pathways — converging on CREB transcription factors that promote neuronal survival, neurite outgrowth, and synaptic plasticity. This is not speculative marketing. It is a mechanistic pathway with preclinical support and growing human data behind it.
The Human RCTs
Mori et al. (2009) — the landmark trial. Thirty adults aged 50–80 with mild cognitive impairment were randomised to Lion's Mane (4 × 250 mg tablets, 3×/day = 3 g/day) or placebo for 16 weeks in a double-blind, placebo-controlled design. At weeks 8, 12, and 16, the Lion's Mane group showed significantly improved scores on the HDS-R cognitive function scale. After supplementation ended, scores declined within 4 weeks — suggesting an active, ongoing mechanism. No adverse effects were recorded (PMID: 18844328).
Saitsu et al. (2019) — a separate RCT in healthy adults (not cognitively impaired). Twelve weeks of fruiting-body supplementation produced significant improvements on the Mini-Mental State Examination (MMSE), as well as improvements on the Benton visual retention test. The researchers noted multiple chemical compounds — including hericenones — likely contribute to effects across neural networks (PMID: 31413233).
Nagano et al. (2010) — an RCT of 30 women showing reductions in depression and anxiety scores after 4 weeks of Lion's Mane cookies (PMID: 20834180). An underappreciated finding: the mood signal appeared before the cognitive signal, suggesting possible HPA-axis modulation alongside the NGF pathway.
La Monica et al. (2023) — acute dosing RCT in 41 healthy young adults. A single 1 g dose of Nordic Lion's Mane significantly improved Serial 7s attempts, N-Back reaction time, and Go/No-go response versus placebo — effects measured within 2 hours. The Lion's Mane group also reported improved subjective happiness at 60 minutes post-ingestion (PMID: 38140277).
Docherty et al. (2023) — a 28-day RCT in 41 healthy adults aged 18–45. A single 1.8 g dose significantly improved Stroop task performance at 60 minutes. After 28 days, a trend towards reduced subjective stress was observed (p = 0.051, approaching significance). Authors noted that null findings also occurred and called for larger sample sizes to confirm (PMID: 38004235).
What This Means in Practice
"The evidence is strongest for mild cognitive impairment and stress-related brain fog — not for healthy young adults seeking a dramatic nootropic boost."
Lion's Mane appears most effective for adults experiencing age-related cognitive decline, stress-induced brain fog, or both. The Mori 2009 and Saitsu 2019 trials provide the strongest support. The acute-dose RCTs (La Monica, Docherty) are encouraging for younger adults but come with caveats — sample sizes are small and not all outcomes reached significance.
Benefits are real but gradual, typically emerging over 4–16 weeks of consistent use at 1–3 g daily.
Who Lion's Mane Likely Works Best For
- Adults 50+ with early cognitive decline or mild memory concerns
- Professionals experiencing chronic stress-related brain fog
- Students during high-demand study periods (acute dose may help)
- Anyone looking to support long-term neurological resilience
Who It Likely Won't Help (Based on Current Evidence)
- Healthy young adults with normal cognition seeking dramatic acute enhancement
- People expecting stimulant-like effects — this is not caffeine
Contraindications: Consult your healthcare practitioner before use if you are taking anticoagulants (Lion's Mane may have mild antiplatelet activity), immunosuppressants, or are pregnant or breastfeeding. No serious adverse effects were reported across the published RCTs, but long-term safety data beyond 16 weeks remains limited.
Best paired with: Quality sleep, regular movement, and omega-3 fatty acids. The evidence for cognitive support is strongest when supplementation accompanies these fundamentals — not as a substitute for them.
Cordyceps: The Energy Evidence Is More Complex Than You Think
Cordyceps works through entirely different pathways. Rather than supporting neurons, it targets cellular energy metabolism. Its primary bioactives — cordycepin and adenosine — are directly involved in ATP production and oxygen utilisation. Cordycepin is a structural analogue of adenosine; it activates AMPK (AMP-activated protein kinase), the master metabolic switch that upregulates mitochondrial biogenesis and fatty acid oxidation.
A 2024 clinical study (PMID: 38673866) demonstrated that a standardised Cordyceps sinensis mycelium extract increased ATP production by 68% in skin cells and boosted NAD+ synthesis — with sirtuin activation (SirT1 +33%, SirT6 +72%) measured in a double-blind, placebo-controlled trial of 40 subjects. While this was a skin-longevity study, it provides direct research suggests benefits for Cordyceps' cellular energy mechanism — the same ATP and NAD+ pathways relevant to physical performance and vitality.
The Key Exercise Performance Trial
Chen et al. (2010) — a double-blind, placebo-controlled trial of 20 healthy older adults (aged 50–75). After 12 weeks of CS-4 supplementation (333 mg × 3/day), the metabolic threshold increased by 10.5% (p < 0.02) and the ventilatory threshold increased by 8.5%. No significant change in VO2 max was observed in either group. Conclusion: CS-4 improves metabolic efficiency at submaximal exercise intensities — which is how sustained endurance works in everyday life — but did not raise absolute VO2 max ceiling in this older adult cohort (PMID: 20804368).
This distinction matters. The research suggests Cordyceps makes you more efficient at the aerobic work you already do, rather than raising your absolute peak capacity. For daily energy, endurance at moderate intensities, and recovery — that is precisely where the benefit lives.
The Broader Research Picture
Beyond exercise, Cordyceps has the most consistent evidence in clinical populations:
- Multiple meta-analyses demonstrate adjuvant benefit in chronic kidney disease (PMID: 36375237, PMID: 25519252)
- A 2024 meta-analysis examined Cordyceps as adjuvant treatment alongside conventional lung cancer therapy with positive findings (PMID: 38484953)
- Honest negative finding: A COPD RCT (PMID: 41295088) found Cordyceps improved some quality-of-life measures but failed to improve FEV1 — the primary lung function endpoint — versus active control
What This Means in Practice
"Cordyceps is not a pre-workout stimulant. It is a metabolic adapter. Benefits accumulate over weeks, not hours."
Who Cordyceps Likely Works Best For
- Adults 50+ experiencing reduced aerobic capacity or afternoon energy crashes
- People recovering from illness or with chronic fatigue
- Those with respiratory concerns (supported by multi-study evidence)
- Recreational exercisers wanting sustained endurance at moderate intensities
Who It Likely Won't Help (Based on Current Evidence)
- Elite athletes seeking measurable VO2 max gains — evidence is inconsistent in trained individuals
- Anyone expecting an acute energy surge after a single dose
Contraindications: Consult your healthcare practitioner if you are taking blood-thinning medication, diabetes medication (Cordyceps may reduce blood glucose), or immunosuppressants. Avoid during pregnancy and breastfeeding due to insufficient safety data.
Best paired with: Regular aerobic exercise, adequate hydration, and iron-rich foods. Cordyceps supports oxygen utilisation — but only if the foundations are in place first.

The Dual-Channel Principle: Why "Both" Is a Legitimate Answer
Here is what most comparison articles won't tell you: because Lion's Mane and Cordyceps operate through completely separate biological channels — the neurotrophic pathway versus the mitochondrial energy pathway — there is no pharmacological rationale against combining them. They don't compete for the same receptors. They don't interfere with each other's absorption. They don't share metabolic pathways.
Think of it this way. Lion's Mane works upstream at the level of gene expression and neuronal architecture. Cordyceps works at the level of cellular ATP production and oxygen metabolism. One builds the hardware. The other powers it.
Important Limitation to Acknowledge
No published human trials have examined this specific combination. We cannot claim synergistic effects — only that the non-overlapping mechanisms make combination biologically sensible. "Biologically sensible" is not the same as "clinically demonstrated."
A practical approach many people find useful: Lion's Mane in the morning coffee or tea for cognitive support throughout the day, and Cordyceps either alongside or before physical activity for energy support. Both dissolve well in hot liquids and pair naturally in a morning ritual.

Why does extraction method matter? Hericenones — the key cognitive compounds in Lion's Mane — are fat-soluble. A hot water-only extract cannot pull them from the mushroom material. Our Lion's Mane uses ethanol as well as hot water, capturing both the fat-soluble hericenones and the water-soluble beta-glucans and erinacines. If you are buying Lion's Mane extract, always check whether it is dual-extracted. Many products on the market are hot-water-only — a meaningful gap in what they deliver.
Our Cordyceps CS-4, on the other hand, is appropriately hot-water-extracted. Cordycepin and the target polysaccharides are water-soluble; ethanol extraction is neither necessary nor beneficial here. Matching extraction method to compound chemistry is the difference between an effective product and an impressive-sounding label.
Honest Limitations You Should Know
We formulate both of these products. We believe in them. And we believe you deserve the full picture — including what the evidence does not show.
- Human vs animal evidence is uneven. The majority of published mushroom studies are in-vitro or animal models. For Lion's Mane, approximately 10 of 567+ published studies are human clinical trials. Much that gets cited as "evidence" comes from mouse models, which do not reliably predict human outcomes. Cordyceps exercise performance evidence in healthy people remains inconsistent.
- Lion's Mane RCT sample sizes are small. The most-cited cognitive trials enrolled 30–50 participants (Mori 2009: n=30; Nagano 2010: n=30). Larger, longer trials are needed to confirm the magnitude of benefit. No large-scale replication of Mori's 2009 findings has been published.
- Cordyceps exercise performance evidence is inconsistent in trained athletes. The Chen 2010 trial showed positive metabolic threshold results in older, untrained adults. Evidence in younger, trained athletes is mixed — some trials show improved VO2 max; others find no significant difference from placebo.
- No combination trials exist. We cannot claim synergy between Lion's Mane and Cordyceps — only that the non-overlapping mechanisms make combination biologically reasonable. "Biologically sensible" is not "clinically demonstrated."
- Most Cordyceps research uses CS-4 mycelium — not militaris or wild sinensis. CS-4 is the most-studied form in kidney and respiratory research, but it differs meaningfully from wild Ophiocordyceps sinensis and from Cordyceps militaris fruiting body. Results do not transfer automatically across preparations.
- Individual responses vary considerably. Some people notice cognitive improvements from Lion's Mane within days; others require 8–12 weeks; some notice nothing. The research supports this variability.
- No Cochrane reviews exist for Lion's Mane cognitive benefits or Cordyceps exercise performance. The gold standard of systematic evidence synthesis has not yet weighed in on either.

Frequently Asked Questions
Can I take Lion's Mane and Cordyceps together?
Yes. They work through completely separate biological pathways — Lion's Mane supports NGF and BDNF in the brain, while Cordyceps influences cellular energy metabolism via AMPK activation. There is no pharmacological conflict. Many people take Lion's Mane in the morning for cognitive support and add Cordyceps before physical activity or alongside it for all-day support. No human trials have studied this combination specifically, so synergy cannot be claimed — but the non-overlapping mechanisms make combining them biologically sensible.
Which is better for energy — Lion's Mane or Cordyceps?
Cordyceps is the better choice for physical energy. It contains cordycepin and adenosine, compounds involved in ATP production and oxygen utilisation at the mitochondrial level. Lion's Mane supports mental clarity and focus — what some describe as "mental energy" — but does not directly influence physical stamina or aerobic capacity. If you want both, the dual-channel principle supports taking them together.
How long before I notice effects from Lion's Mane?
Two timelines exist. Acute effects (reaction time, processing speed) have been demonstrated within 1–2 hours of a single dose in two RCTs (PMID: 38140277, PMID: 38004235). Sustained cognitive benefits — particularly for memory and overall cognitive function — typically emerge over 4–16 weeks of consistent daily use (PMID: 18844328, PMID: 31413233). Individual responses vary considerably. If you notice nothing after 12 weeks of consistent use at 1–3 g daily, it may not be the right fit for your situation.
What is the difference between Cordyceps CS-4, Cordyceps militaris, and wild Cordyceps sinensis?
CS-4 is a mycelium liquid culture derived from Cordyceps sinensis — the most-studied form in clinical trials, particularly for kidney disease and respiratory conditions. It is also the only commercially scalable form. Cordyceps militaris is a cultivated species (different from sinensis) that can be grown as fruiting body and is typically higher in cordycepin. Wild Ophiocordyceps sinensis (the original "caterpillar fungus") is prohibitively expensive and largely unavailable at supplement scale. Teelixir uses CS-4 — the form with the most human preliminary research and consistent quality testing.
Does Lion's Mane help with anxiety?
There is limited but positive human evidence. Nagano et al. (2010) found significant reductions in anxiety and depression scores after 4 weeks of Lion's Mane in a placebo-controlled RCT of 30 women (PMID: 20834180). Docherty et al. (2023) found a trend towards reduced subjective stress after 28 days (PMID: 38004235, p = 0.051). The mechanism may involve HPA-axis modulation alongside the NGF pathway. This is not TGA-approved evidence for treating clinical anxiety — consult your healthcare practitioner for that — but the signals are promising for everyday stress and mood support.
